Chinese drone maker DJI is the latest company added to the US trade blacklist, throwing its future into uncertain territory.

The US and China have been locked in a costly trade war, one that has involved casualties on both sides. The US has blacklisted Huawei and ZTE, claiming the telecom companies represent a threat to national security.

Now the US has added DJI to the U.S. Department of Commerce’s Entity List, according to Digital Trends. Being on the Entity List means that US companies can’t do business with DJI without a special license. The US is concerned about data Chinese companies could collect on US citizens, as well as drone technology being used in China’s persecution of ethnic minorities.

DJI says customers can still purchase its drones, as being on the Entity List primarily impacts the company’s ability to sell to other businesses.
